Power Spectrum in the Conductive Terrestrial Ionosphere

Power Spectrum in the Conductive Terrestrial Ionosphere DOI:  https://doi.org/10.30564/jees.v2i1.1763 Abstract Stochastic differential equation of the phase fluctuations is derived for the collision conductive magnetized plasma in the polar ionosphere applying the complex geometrical optics approximation. Calculating second order statistical moments it was shown that the contribution of the longitudinal conductivity substantially exceeds both Pedersen and Hall’s conductivities. Experimentally observing the broadening of the spatial power spectrum of scattered electromagnetic waves which equivalent to the brightness is analyzed for the elongated ionospheric irregularities. It was shown that the broadening of the spectrum and shift of its maximum in the plane of the location of an external magnetic field (main plane) less than in perpendicular plane for plasmonic structures having linear scale tenth of kilometer; and substantially depends on the penetration angle of an incident wave ...

Statistical Characteristics of the Temporal Spectrum of Scattered Radiation in the Equatorial Ionosphere DOI:  https://doi.org/10.30564/jees.v5i1.5442 Received: 2 February 2023 | Revised: 6 March 2023 | Accepted: 13 March 2023 | Published Online: 13 April 2023 Abstract On the basis of the solution of the space-time characteristic system by the method of geometric optics using symbolic calculations, analytical and numerical simulation of the propagation of the ordinary and extraordinary radio waves in the conducting equatorial ionospheric plasma was made considering the anisotropy of plasma irregularities and non-stationary nature of propagation medium. Broadening of the spectrum and the displacement of its maximum contain velocity of a turbulent plasma flow and parameters characterizing anisotropic plasmonic structures. Statistical moments of both radio waves do not depend on the absorption sign and are valid for both active and absorptive random media. Temporal pulsations and cond...
